水利水电工程施工中的边坡开挖支护技术分析

Analysis on Slope Excavation and Support Technology in Construction of Water Conservancy and Hydropower Project

水利水电施工是一项较大型工程,为确保施工进度及施工质量,常采用边坡开挖支护技术保障各材料可有效运输到施工现场,为整个工程质量提供支撑。因水利水电工程所处位置关系,边坡位置大多复杂多变,加大了施工难度,部分工程可能因边坡施工不当而延误工期。边坡是保障路基稳定的坡状结构,其施工质量直接关系到施工人员能否利用边坡实施后续操作。完整的边坡开挖支护操作由前期支护、爆破、排水、边坡支护几个步骤组成,不同步骤涉及到的技巧及施工操作均存在差异性。以水利水电工程施工为主线,阐述边坡开挖支护的意义,分析常见的边坡开挖方式及支护技术,并在此基础上研究边坡开挖支护技术的实施步骤。

Water conservancy and hydropower construction is a large-scale project.In order to ensure the construction progress and construction quality, the slope excavation and support technology is usually used to ensure that all materials can be transported to the construction site effectively and provide support for the whole project quality. Due to the location relationship of water conservancy and hydropower projects, the slope position is mostly complicated and changeable, which increases the difficulty of construction. Some works may be delayed due to improper slope construction.Slope is a stable slope of the road structure, the construction quality is directly related to the construction staff can use the implementation of follow-up operation of the slope. The complete slope excavation support operation consists of several steps ： pre-support, blasting, drainage and slope support.There are differences in the skills and construction operations involved in different steps,This paper briefly introduces the significance of slope excavation and support, analyzes the common excavation method and support technology, and studies the slope excavation and support technology on the basis of this practical steps.
